tl1at will enable skilled artisans to make a;nrl use 'ohe same, reference being had to the accompanying drawing, and 130 the lette1s of reference marked thereon, lnnklng part of tl:is specificzmtion.

'1his invention relutes 120 a corder-foot fox sewingmachines, constructed as hereinafter described.

Figure 1 is a perspeutive view 0f my improvccl corcler, atzmched 130 the clotl1-presser of a. Wl1eeler 85 Wilson sewing-machine.

Figure 2 is a perspective view of t-he corder invertecl.

Figure 3 is a plan view of the Same inverted.

Fignre 4 is a freut end view.

All tl1e figures are enlarged representations, in or-- der to mute clearly show tl1e seveml parts.

Sinnlar letters of reference indlcate corresponding parts in t-he several figures.

'llle corder may be made of metal er glass, in the f01'rnslxown.

A is the neeclle-hole 01 tl1loat.

B, G, D, and E, are guides, that serve so glve dimetion 150 the fabrie und eord'as thy are dmwn into the machine.

"'lhe nnder face of' tl1e corder is made witl1 a sanken plane ao F, to prevent the feed-points fr0m mising lt -ofi" tlle fabric. lhis sunken part; extends to the outer edge 0f l1e corder, as shown.

'lhe fabrio amd cord are fed through the machine as in ordinany sewing; tl1e groove G, tl1at receives t-he part to 136 operated upon, being wideued and deepened in the front end 150 admit the fabric amd cord freely, and so formed, near the needlelwle, as to press the cord fnymly into the fabric, and ab the same tixne lkeep it wund. and full The guide E serves t-o keep the fabrlc in line after belng stitched, and t0 aid in giving proper directinn 120 that which follows.

In order t prevent the fah1lc from being crimped. as it pnsses tlnough Ll1e corde1, tlw, guicle B 'ts macle to project below the guides O, D, and E, about tl1e thickness 0f ordinary muslin, so as t0 relieve l7l1e pressure of these guides upon t-l1e fabric.

The groove H is of fise only when a. number of cords is lltld close together.

Immediately surrounding; t-he needle-hole tl1e groove G is ma.de quit6 slmllow, grzuluzmlly deepening and widening as it approzwhes tl1e ends of' tlxe corder. Tl1e objeet of this oonstruct-ion is to give tl1e grea.test pressur e npon tl1e fabric at tlxis point, so aus to hold it; firmly against tl1e thrust of tl1e. needle, and t0 press tl1e cord firmly into&lze fa.brio.

'lhe curve is glven to the grooves and guides in order 130 earry tlxe fabrio a.nd cord aronnd the feedpoints filmt are situated in fi'0nt 0f tl1e needle.

When this corder is applied to sewing-rnaclnines lmving bat ons Set 0f' feed-points ab tl1e side of the needle, tl1e sanken part; F need not be cut away so mach, lezwing t-he guide D t0 extend further back toward tl1e needle-hole.

There is no necessity for folding or creasing the fabric where the cord is 130 be la.id, aus wlth othercorders.

Ha.ving thus fully deseribed mylnvention,

Wlmt 1 ela'nn as new, am] desire to seeure by Letters Patent, is-

'lhe corder, furnished witl1 the curved longitudinal grooves'G and H, a.nd guides B, O, D, md E, coustructed and arranged substanlzlzplly as and for th e purpose Sei; folth.
